Optimization not working since last Year but it does work in more time.

[Kenmei Miyamura]

Hello

In this example you can see that if i do an optimization since 2019.06.13 it only shows 1 round in the Optimization Resaults and takes only 22 sec to complete it. 

However if I do the same Optimization since 2018 or before it does work fine showing all the combinations and its resaults, taking almost 9 minutes .

What am I doing wrong ?

Thanks
